SLES145B – AUGUST 2005 – REVISED MARCH 2008

Separate power supplies are recommended for the digital and analog sections of the board. This prevents the

switching noise present on the digital supply from contaminating the analog power supply and degrading the

dynamic performance of the DACs. In cases where a common 5-V supply must be used for the analog and

digital sections, an inductance (RF choke, ferrite bead) should be placed between the analog and digital 5-V

supply connections to avoid coupling of the digital switching noise into the analog circuitry. Figure 35 shows the

recommended approach for single-supply applications.
